Description

Technical Field

[0001] The utility model relates to the technical field of a cleaning device for a spray dryer for casein processing, and more specifically to a cleaning device for a spray dryer for casein processing. Background Art

[0002] Casein is a phosphorus-calcium binding protein that is sensitive to acid and will precipitate at a low pH. Casein is the main protein in mammals including cow, sheep and human milk. It is also called casein, casein, and lactocasein. Casein is a source of amino acids, calcium and phosphorus for young children. Casein forms curd in the stomach for digestion. A spray dryer is required for casein processing. The spray dryer needs to be cleaned after use. Most of the existing dryers are cleaned manually, and it is not easy to clean the residues adhering to the inner wall of the dryer. The accumulation of residues for too long will affect the working efficiency of the dryer.

[0003] Patent authorization number CN213591301U discloses a cleaning device for a spray dryer for casein processing, which can clean the inside of the dryer body to prevent impurities from adhering to the inner wall of the dryer and affecting the working efficiency of the dryer. When cleaning the inside of the dryer, the blower can absorb water mist or dust to avoid polluting the environment.

[0004] However, patent authorization number CN213591301U can repeatedly oscillate the outer wall of the dryer body by setting an oscillation box to avoid excessive accumulation of residues adhering to the inner wall of the dryer body, which is difficult to clean. Although the attachments adhering to the inside of the dryer body can be cleaned by the oscillation effect, the cleaning effect is not ideal for some firmly adhered attachments, which can easily lead to incomplete cleaning. Therefore, we propose a cleaning device for a spray dryer for casein processing to solve the above-mentioned problems. Utility Model Content
